Lunt 152mm Doppler True Solar Telescope w/ Choice Of Blocking Filter & Focuser - LS152THa 

The Lunt LS152THa Solar Telescope stands as the largest solar telescope presently available, offering an unparalleled balance of resolution and performance.

Featuring a 100% unobstructed system, it offers outstanding performance at both low and high magnifications. 

This telescope is not only ideal for visual observations but also serves as a powerful tool for high-end digital processes, providing users with a versatile and top-tier solar observation experience.

The incorporation of advanced high-contrast coatings and the innovative Doppler True Pressure Tuning system ensures crisp, sharp, and high-magnification optical images. 

Every Lunt Solar Telescope requires a blocking filter for safe operation. Select the right one for your needs:

  • B1200 (12mm Blocking Filter) – for visual use
  • B1800 (18mm Blocking Filter) – for larger field of view and imaging applications
  • B3400 (34mm Blocking Filter) – for larger field of view and imaging applications with larger sensors
  • No Blocking Filter Warning – only choose this package if you already have a Lunt Solar Systems blocking filter at your disposal.  All Lunt Solar Systems h-alpha telescopes require a Lunt Blocking Filter.

True Doppler Tuning:

This technology enables a dynamic shift into and away from the user, adding a 3D-like dimension to the viewing experience.

True Doppler Tuning, an innovative feature of the Lunt Solar Systems LS152THa Solar Telescope, elevate your solar observations to a  peak performance level.

While its impact on prominences is minimal, it significantly affects filaments and active regions on the solar surface.

When observing a filament at the solar center, users can Doppler shift from the base to the tip, tracking the filament's structure in both directions.
